What makes a Ball Bend (Soccer) I have 5 fake facts.

To know how a curves in the air. You must know a ball travels through the air. The ball travels through the air by a vertical (upward) force . To make the ball spin in the air, you have to add the force of spinning. To add the force of spinning, you have to kick the ball with the technique called outside outstep kick. When the ball bends, it can curve and drop suddenly. This is called a drop ball. A regular path which the ball travels is called a parbola form the conin section of Algerbra that looks like a half of a circle.
To bend the ball you need vertical and spinning forces exerted at the same. When the upward force dies out, the spinning creates a whirlpool of air. This creates a downward force acceleration on itself. This creates the bending and drop.This is also known as the Magnus effect.
